Having personally been introduced to the band on a past tour with Pain of Salvation, I find it easy to compare them to the Swedish masters. Vocalist Diego Marchesi isn't as flamboyantly charismatic as Daniel Gildenlow but he excels at delivering some tricky yet catchy vocal lines. In addition, Kingcrow makes good usage of atypical rhythms, flamenco acoustic guitar work, and a sense of drama that are right in line with the best of The Perfect Element and Remedy Lane.
Of course, there are other influences at work here. The heavy guitar tone is similar to late era Porcupine Tree, the swells remind one of Anathema's lighter efforts, and traces of Opeth and Dream Theater are used to fill in the gaps.
I'm unfamiliar with Kingcrow's other works but Eidos is a powerful effort that pulls from the best of modern prog. Its easily identifiable influences may lead some to deem it too derivative and its connection to metal is loose at times, but the songs are well written enough to make this a highlight for the year. Here's hoping they'll achieve the acclaim that's been long overdue.
